Abstract: Methods, systems, and devices for data management are described. A custodial token platform may determine whether one or more crypto tokens associated with a user account at the custodial token platform satisfy a criteria. The custodial token platform may display a user interface including an indication that staking is available for a first crypto token based on the first crypto token of the one or more tokens satisfying the criteria. The custodial token platform may receive one or more inputs from a user via the user interface, including an input that indicates an amount of the first crypto token to stake. The custodial token platform may generate messages configured to stake the amount of the first crypto token via a blockchain network associated with the first crypto token. Further, user may opt in to automatically stake future crypto tokens received by the user account and that are eligible for staking.

Abstract: Techniques are described that determine a user to participate in software testing of a social network application and/or service and to enable the user to propagate an invitation to contacts of the user to participate in the software testing of the social network application. In some examples, the user may be provided a message via an inbox of a first service including the invitation and a selectable option to install an application associated with a second service. In some, examples, the user may be sent a list of contacts from which the user may select other users to also participate in the software testing of the social network application. In some examples, responsive to the user's selection, a message may be sent to an inbox of the selected contacts that contains an invitation to participate in the beta version of the social network application.
